The theory of general relativity upended the world of physics and even its author resisted accepting a bizarre phenomenon the ...

The James Webb telescope peers through a warped bubble of space-time to study galaxies from the first billion years after the ...

Why is the expansion of our Universe accelerating? Twenty-five years after its discovery, this phenomenon remains one of the greatest scientific mysteries. Solving it involves testing the fundamental ...

In a new study published in Classical and Quantum Gravity, researchers have revisited the concept of Einstein-Rosen bridges, the theoretical structures often associated with wormholes. This study, ...

Dark energy revived Einstein’s discarded cosmological constant and reshaped the leading model of the universe.

Some of the hardest questions in cosmology begin where the usual math gives up. Push Einstein’s theory far enough back toward ...

According to current understanding, the universe is expanding—and is doing so at an accelerating rate. This is believed to be ...

For over a century, Einstein's general theory of relativity has been key to understanding gravity. But new research suggests this theory "glitches" in the farthest reaches of space. That doesn't mean ...

Research teams on both sides of the Atlantic have shown that precise modeling of the universe and its contents will change the detailed understanding of the evolution of the universe and the growth of ...

For more than 20 years, scientists have believed that the universe is expanding at an accelerating rate due to mysterious dark energy, an invisible form of energy that, according to modern ...
